To all whom it may concern:

Be it known that I, DIoKERsoN G. BAKER, a citizen of the United States, and a resident of VVillimantic, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Thread- VVinders, of which the following is a full, clear, and exact descriptiomwhereby any one skilled in the art can make and use the same.

My invention relates to the class of machines used for winding bobbins or the like which have an extended use in connection with sewing-machines; and the object of my invention is to provide a machine of this class which shall have increased facilities for turning off work both as to the amount of work done in a given time and also as to the quality of the work produced.

To this end my invention consists in the device as a whole, in the combination of parts making up the device, and in the details of such parts and their combination, as hereinafter described, and more fully pointed out in the claims. v

Referring to the drawings, Figure 1 is a detail front or end view of my vimproved thread-Winder with 'the parts in relative position at a preliminary step in the operation of Winding. Fig. 2 is a detail top view of that end of the machine containing the windingspindle and thread-guide. Fig. 3 is a front or end view of the machine, showing the position of the guide With reference to the spindle when the bobbin is nearly wound. Fig. 4 is a detail view showing the means for holding the guidesupport in its swinging movement. Fig. 5 is a side view of the machine. Fig. G is a'front or end view of the machine, showing the relative position of the parts when a bobbin is nearly Wound, but in this instance the spindle containing the bobbin being moved away from the guide.

Various forms of machines may be employed the mechanism of which will embody my invention, a simple device for carrying out the main features being described herein and illustrated in the drawings, in which the letter a denotes the base of a machine, Z9 a standard thereon, and c a main shaft driven from any suitable source of power, as by means of a belt d, passing over the pulley c.

lrojections b' of cylindrical form extend from opposite sides of the standard ZJ, an opening for the shaft c extending through the standard and these projections. If desired, the projections may consist of a sleeve located within the standard and projecting 011 opposite sides thereof.

A winding-spindle support e, mounted on one of the projections b', extends upward above the standard and supports above the standard a winding-spindle f. This windingspindle is provided with any suitable means for retaining thereon a core upon which a mass of thread is formed, a gear f on the spindle meshing lwith a winding-spindle gear c2 on the main shaft c.' A guide-support gis constructed in the form of a gear-casing and is located on a projection b',preferably on the opposite side of the standard from the winding-spindle support e. The upper end of the support g bears a guide-stud h. A rotary guide 7o is rotatively mounted at the upper end of the guide-support, and a gear 71, is operatively connected with the guide.A It is also connected with the guide-gear c3 on the main shaft by means of an intermediate gear i. In the form of the device shown the gears c3, h', ande' are located in a recess in the guide-support that forms a casing for the gears. The guide-stud 7i is secured in the upper end of the guide-support, the gear h' being rotatively mounted thereon and having a hub, ou which is secured the guide k. I contemplate any means, however, for operatively connecting the guide and gear aud do not limit myself to this precise form.

The supports e and g are located on the projections h' in a manner to have a swinging movement thereon, a device that will allow the supports to have a swinging movement under pressure being employed, this device, however, being su ficient to hold the support in any position once attained.' One form of device for accomplishing this result is shown herein, consisting of a clamp-screw g', located in the guide-support g, its inner end resting against a block g2, a shoe, preferably of leather or other fibrous material, being located between the block and the projection l2'. It is understood thata similar device is used in connection with the support c.

The rotary thread-guide 7u is round in form and bears in its periphery a guide-slot 7c', extending in a helical path part way only around the guide and then backward in a like pathto the point of beginning. A bridge l, consisting of ahood-like extension, projects from the guide-support g in a position adjacent to the guide k and may be secured to the guide-support in any suitable manner. This bridge underlies the thread-guide and extends upward in a position between the guide and winding-spindle, the edge of the bridge being preferably so located as to cause the th ead to pass from the guide over the edge or the bridge onto the bobbin.

In the operation of winding the thread passes through the guide-slot in the guide over the edge of the bridge and onto the Winding-spindle, the winding-spindle and guide being rotated with especial reference to each other to produce the kind of wind desired. An important feature of invention in connection with the rotary thread-guide resides in maintaining the same angular velocity of the guide and bobbin with respect to each other throughout the entire operation of winding, and by angular velocityI mean that the number of revolutions of one part with respect to the other during a given period shall be maintained. Thistermangularvelocityis distinguished from peripheral velocity as in a case where one body is rotated by direct contact with another, one of which gradually increases in size, in which case the revolution of the part increasing` in size would decrease in speed with respect to the opposite part as the operation proceeded. This is an objection in devices where the guide is rotated by direct contact with the bobbin,as it is obvious that by changing the relative angular velocity of the two parts the traverse is changed and would not be the same at the completion of the winding of a bobbin as when the operation began.

In this class of devices it is of advantage to have the guide and the windingspindle operated from a single source, such a construction enabling the degree of relative rotation of the parts to be easily graduated to a nicety. In such a device it is desirable to rotate the guide slightly faster than the winding-spindle in order that the thread in its spiral wrap about the bobbin shall be carried forward to a slight degree and thus prevent the objectionable feature of the tendency of the thread as it wraps about the bobbin to ride over that part previously wound thereon, as is the case where the bobbin and guide are rotated at the same rate. Such objection is easily obviated in a machine of this description by varying to a slight degree the number of teeth in the gears between the driving-shaft and the winding-spindle or guide-spindle, as it is obvious that this change must be very slight. In winding some forms of thread, as on a bobbin of considerable length, it is found desirable to lnove the sp'indle away from the guide instead of the guide away from the spindle, and in the form of the device herein shown I have provided means whereby this result may be obtained, the spindle being moved away from the guide or the guide moved away from the spindle, as desired.
